IMPROVEMENT IN SOLDERING--FURNACI-Z.

Letters Potent No. 90,987, dated June S, 1869.

The Schedule referred to in these Letters Patent and making part of thesam'e.

To all whom it may concern.:

Be it known that we, J ons G. lonDuN and WM.- TER POWER, of BrewsterStation, in the county ol' Putnam, and State of New York, have inventeda new and improved Soldering-Machine; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others` skilled in the'art to make and use the saine, referencebeing had to the accornpanyingr drawings, forming part ofthisspecification, in which- Fignre 1 is a top or plan view olonr improvedinachine.

Figure 2 is a vertical cross-section of tno same, taken through the linex ft', lig. 1. l

Figure 3 is adctail longitudinal section, taken through the line L1/ 1/of fg. l.

Similar letters of reference indicate corresponding parts.

Our invention has for its object to furnish an iniproved machine, bymeans of which the heads of sheetlnetai cans may be soldered to theirbodies quickly and thoroughly, and withont waste or undue use of thesolder.

And it consists in the construction and combination of various parts ofthe machine, as hereinafterl more fully described.

A represents the stove or furnace, about the construction of which thereis nothing new.

B are two chambers, formed upon the top of the l top plate C of thestove or furnace, and at a distance apart a little more than the lengthof the cans to be soldered, as shown in l and 2.

Into the chambers B is put the solder to be melted. As the solder melts,`it flows through openings in the lower part ofthe partition-walls intothe chambers D, formed along the inner sides of the chambers B, and madeof suoli a size as to contain the soldering-tools E.

This manner of introducing the solder into the chambers D whollyexcludes the dross which is left in the chambers B. f

rlhe soldering-tools are made in about the form and manner shown in 1,2, and 3, that is to say, the upper edge of their forward ends areconcaved to correspond somewhat with the curve of the cans, and theirouter ends project ont beneath the projecting ends of the rest F,attached to the forward part of the plate top C, where they areadjustably heldin place by set-screws G, passing down through the saidprojecting ends of the rest ll.

lhe soldering-tools are kept hot by the heat of the chambers l) and ofthe melted solder in said 'chainbers, and feed the solder to the seamsof the cans to be soidered bythe attraction between their tinned endsand the said solder.

11 is a chamber or spout formed between the two chambers 1.), to receiveany solder that may overflow from the said chambers D, and conduct itint-o the chamber I, formed in the rear part of the top plate C.

The chambers D are also connected with the chamber l by small channels,as shown in dott-ed lines in figs. l and 3, to prevent the said chambersD from becoming too full. y

The melted solder that accumulates in the chamber I may be dipped backinto the chambers B when required.

lhe middle parts of the upper edges of the partitions between thechambers B, D, and H, are hollowe-d out, or concaved, to correspondsomewhat with the curve ofthe cans to be soldered, as shown in tig. 3.

The cans, while being soldered, are held between the centros' or heads Jand K, and are revolved by the revolution of said heads .or centres.

The shaft L of the head J revolves iu bearings in the standard M, at theside of the stove or furnace A, without longitudinal movement, and has acrank or pulley il attached to it, by means of which it may receivemotion from hand or other power.

The shaft O of the centre or hcad K revolves in bearings in the standardl, at the other side of the stove or furnace A, in such a way as to bothrevolve and have a longitudinal movement.

The outer end of the shaft O is rounded olf, or made pointed, and restsagainst the upper end of the lever Q, which is pivoted to supports R,attached to the standards P, and the lower end of which inclines inwardtoward the lower part of the said standard P,

as shown in lig. 2, so as to form a wedgelshaped space between the saidstandard and lever.

S is a lever, the rear end of which is pivoted to some suitable supportat the side of' the rear part of the stove or furnace A.

The lever S passes through the wedge-shaped space, between the standard'P and lever Q, and its forward end extends out int-0 such a positionthat it may be conveniently reached and operated, so that, by forcingthe said lever S downward, the head or centre K will be forced forwardto clamp the can to be soldered between the heads or centres J and K.

When the lever S is raised, the head or centre K is withdrawn from thecan, by a coiled or equivalent spring, l, :onnected with the shaft O.

'U is a spring, upon which the can rests while heilig soldered, andwhich should be of suliicient strength to raise lthe said can whenreleased from the heads or centres J K, and allow it to roll down theinclined guide` way V, which is attached to the top plate O, toconductthe soldered cans out of the way.

Having thus described our invention,

We claim as new, and desire to secure by Letters Patent* 1. The topplate C of a stove or furnace, provided with chambers B, D, H, and .1',constructed and zur* .ranged snbstmltizrlly as herein shown unddescribed,

and for t-he purpose set forth.

2. The combination of t-he heads or centres J K, and shafts L P, withthe top plate C, provided with the chambers B, D, H, and I,substantially :is herein shown and described, and for the purpose forth.

3. The soldering-tools E, in combination with the chambers D of the topplate C, and with the heads 0r centres J K, substantially as hereinshown and described, and for the purpose set forth.
